A T ToZA/EY Patented Apr. 22, 1952 UNITED STATES PATENT OFFICE 8 Claims.

This invention relates to the printing andbinding arts, and it has particular reference to a padding or tabbing rack for paper stock, and its principal object resides in the provision of a device for supporting stacks of paper stock which has been prepared for binding or gluing into pads of uniform or predetermined thicknesses, as printed forms, bank checks and drafts, memo pads, and the like, and secure the sheets of the stock in proper alignment in the stacks to facilitate the gluing operation.

It is an object of the invention to provide a padding rack of simple and economical design which is capable of accommodating stacks of paper stock out into uniform sheets of different sizes and provide means for aligning the edges of such sheets to insure precision in their unitary assembly into pads and for the'application of a padding compound, or other suitable binding materials, to their edges on one side of the stack.

Another object of the invention is that of providing a rack which is pivotally supported on a movable base so that it is capable of being loaded from one side, which is open, and afiording racking or guide doors on the opposite side, against which the stock is arranged and properly aligned, and which can be opened or swung back to expose the secured stocks for gluing.

A still further object of the invention resides in the provision of a padding rack which is capable of being inclined from a vertical position on either side of its pivotal axis, and rearwardly thereof, to more readily retain the stacked paper stock while the same is secured by adjustable clamps for the gluing operation.

While the foregoing objects are paramount, other and lesser objects will become manifest as the description proceeds, taken in connection with the appended drawings wherein:

' In conventional padding operations it is common practice among printers to arrange the prepared paper stock in suitable stacks on tables, using \weights, and other devices, for retaining the stacks in proper alignment for the application of the padding compound. Such facilities are impractical and unsatisfactory because it is difficult to maintain the stock in proper alignment and there is the hazard of losing the stack under the crowded conditions of some shops. Moreover, the 01d method of stacking the stock on bindary tables for tabbing usually consumes valuable space and time.

The present invention is designed to afiford a readily movable racking case which is so mounted as to provide a mechanism capable of being operated with great ease and by persons who need not be particularly skilled in the printing art, because the device affords a means for retaining the stock so that it is substantially self-aligning, requiring a minimum of manual effort. It will also become apparent that a plurality of stacks of different size sheets can be processed in the device at one operation.

The invention, therefore, comprises a rectangular frame or case I0 adapted to be positioned and operated in substantially vertical positions. The case I I] has closed sides II and I2, and top and bottom members I3 and I4, the operative sides of the case I0 being open except for a pair of guide doors I5 and I6 attached by hinges I! to the side members II and I2 to partially close the padding side of the case, as illustrated in Figures l and 7.

The doors I5 and I6 are shown in open position in Figure 5, the hinges I] being sectional and having double pivots IB so that the doors I5 and I6 can be swung well back on either side of the case. Tensioned latches; I97secure the doors I5 bolts 33.

3 and I6 at the top and bottom of the case III while the stock is being placed therein.

The case It) is pivotally supported by a spindle 2| attached by a flange 22 to the bottom I4 thereof, the lower end 23 of the spindle 2| being rotatively seated in a bearing :24 in a base 25, the latter having a plurality of casters 25' to facilitate moving the assembly. The base 25 has a front portion 26 on which is defined a plurality of shallow compartments 21, 28 and 29, by embossed ribs 30, to accommodate certain accessories, such as glue and water pots, extra clamps, and the like. An open frame portion 3| extends rearwardly from the portion 26 and supports a standard 32 which is secured thereto by bolts 33.

The standard 32, shown more clearly in Figi ures l, 2 and 6, comprises a casting formed with angular sides 34 and suitable angular bracing members 35. Foot members 36 provide means for securing the standard 32 to the base 25 by the To the upper end of the standard 32 is secured a guide frame 31 by bolts 38, the frame 31 being shown in detail in Figure 3 and which will be presently described.

Secured to the top I3 of the case In is a casting 39 which is formed with a flange 40 for attaching the same by bolts, or other suitable device. Integral with the upper end of the member 39 is an annular flange or ring 4| which provides a pivot for the upper end of the case ID. The guide frame 31, a plan view of which is shown in Figure 3, is for-med with a plurality of semi-circular recesses with which the member 4| conforms. When the pivot member 4| is located in the recess 4'2, forwardly of the frame 31, which is in vertical alignment with the bearing 24 on the base 25, the case II) can be rotated on its pivots 2| and 4 Directly behind the recess 42 is another similar conformation 43 which will receive the member 4| to permit the case III to be inclined in the manner shown in Figure 6. When the member 4| is placed in either of the recesses 44 and 45 the case ID can be inclined to either side, as illustrated in solid and dotted lines in Figure '1. The flanged member 4| has a pair of diametrically opposed slots 46 into which is arranged a threaded rod 41, one end of which is connected to a hinge 48 which is pivotally secured between a pair of brackets 49 attached by bolts 50 to the guide frame 31 rearwardly fromthe recess 42.

The opposite or free end of the rod 41 is arranged, when the case I0 is locked in a vertical position as in Figures 2 and 3, in a notch 5| defined by a pair of integral spaced lugs 52 on the front of the frame 31, the nuts '53 and 54 being adjustable along the rod 41 to properly space the same. Thus, the case I0 is rigidly secured against rotation or against displacement from the recess 42. The case can be locked in rigid position in the same manner when turned 180 degrees, or reversed on its pivots 2| and 4|. The rod 41 is also employed to rigidly lock the case II) in the inclined position shown in Figure 6, or when the member 4| is in the recess 43.

In operation, therefore, the case I0 should be positioned so that the guide doors I5 and I6 are to the rear, as depicted in Figures 1, 2 and '7, which shall be hereinafter referred to as the loading position. In such position the stock 20, which is cut into sheets of uniform size, is stacked and secured by one of a pair of clamps 55 which are slidably attached to the sides II and I2 by bolts 56 arranged in the slots 51 defined between steel strips 58 secured to the inner surfaces of the side members II and I2, as shown in Figure 4. A groove '59 is provided longitudinally of each of the side members I I and I2 to accommodate the heads of the bolts 56 and winged nuts ISII are threaded upon the bolts 56 by which the clamps are rigidly secured against the stacked stock 20.

Each of the clamps 55, which are interchangeable, has an auxiliary clamp or plate 6| suspended therebeneath by screws a, b, c, and d, and when the clamps are impressed upon the stock 20, the plate members 6| can be manipulated to more securely hold the stock inposition by the thumb screws 62. The clamps 55 are shown in Figures 1, 4, 5 and 7, and can be removed from the slots 51 at their lower ends which are spaced above the bottom I4 sufficiently to release the bolts 56.

One of the objects of the invention is that of providing a medium through which the stacked paper stock can be properly aligned and it is often desirable to jog the stock againstone of the sides and one of the guide doors. This can be more readily accomplished by tilting the case In to either side of its axial pivots, in the manner shown in Figure 7, as previously described. It is apparent that when one stack is secured in the case I0 the latter can be tilted to the opposite side, as illustrated in dotted lines in Figure '1, and another stack installed.

vAfter the stock 20 is properly arranged in the case the upper pivot 4| is returned to the recess 42 and the case Ill rotated degrees to bring the doors I5 and I6 to the front of the structure and the latching rod 41 is placed in operative position to hold the case rigid. The doors I5 and 6 can then be opened and the padding compound applied to the stock 20. In this position the stock is fiush with the edges of the side members I I and I2 and the bottom I4. The stock is divided into units by separating boards 63 which may be employed as backing boards for thepads.

When two stacks of stock of different dimensions are to be processed in the case It, and one stack is composed of larger sheets than those of the other stack, an auxiliary clamp of lesser dimension may be substituted for one of the clamps 55, the other of which may overlap the smaller sheets while the smaller clamp is used to depress the sheets of lesser dimension in the companion stack. The auxiliary clamp can be deposited in the central compartment 28 on the base 25, the compartments 21 and 29 being provided for the glue and water pots 64 and 65, shown in Figures 6 and 7. The device can be made stationary by locking the casters 25' by any suitable device, such-as the members 66.

Obviously, certain modifications in the structure can be resorted to by persons skilled in the art, and certain accessories may be added without departing from the spirit and intent of the I invention or the scope of the appended claims.
